如何烘乾Capistrano食譜？

Question

我正在使用Ruby on Rails和Capistrano創業板。我想幹（不要重複自己）一個Capistrano食譜。

在deploy.rb文件我有：

# First task 
task :first_task do 
    ... 

    run "cd #{current_path}; #{try_sudo} chmod -R 666 /log/production.log" 
end 

# Second task 
task :second_task do 
    run "..." 

    # The following code is equal to that stated in the first task. 
    run "cd #{current_path}; #{try_sudo} chmod -R 666 /log/production.log" 
end 

那麼，如何我乾的上述代碼，以便有沒有重複的任務？

Capistrano的代碼僅僅是Ruby代碼與領域特定語言（DSL），所以你應該能夠做到：

def chmod_log 
    run "cd #{current_path}; #{try_sudo} chmod -R 666 /log/production.log" 
end 

# First task 
task :first_task do 
    ... 

    chmod_log 
end 

# Second task 
task :second_task do 
    run "..." 

    # The following code is equal to that stated in the first task. 
    chmod_log 
end
